1000000 x 1000000= what?

Answers

Answer:

1000000000000

Step-by-step explanation:

1000000x1000000=1000000000000

The solution of the expression 1000000 x 1000000 in exponential form is  [tex]10^{12}[/tex].

A collection of constants, variables connected using one or more arithmetic operator is called an expression.

Example = 4y, 3x+4.

The way of writing or expressing a number in powers is called exponent.

Example: [tex]3^2[/tex]

Here, 3 is the base and 3 is the power.

The given expression can be written in the index  or exponential form as:

1000000 x 1000000 = [tex]10^6 \times 10^6[/tex]

Since, the given exponent has the same base.

So, using the law of exponent, it can be written as:

[tex]a^m + a^n = a^{(m+n)[/tex]

[tex]10^6 \times 10^6 = 10^{(6+6)}[/tex]

                  = [tex]10 ^{12}[/tex]

Thus, the solution of the expression 1000000 x 1000000 in exponential form is [tex]10^{12}[/tex].

How do you write (4)(25)-300 as an addition equation

Answers

4 x 25 + - 300 is a way u can do it

(4)(25) - 300 can be written as an addition equation: 100 + (-300).

What is an equation?

An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.

Given:

An equation is (4)(25)-300.

To write (4)(25)-300 as an addition equation,

we can break it down into two separate addition equations as follows:

(4)(25) - 300 = (4)(25) + (-300)

To solve this further,

substitute the value 25 x 4 = 100 to the above equation, we get,

= 100 + (-300)

Therefore, the equation in the required form is  100 + (-300).

Find the expression with a value of 30;

 when x  = -1 and y = 3:

   A.  (x - 3²).y-6

           (-1 - 9).3-6 = -10 x 3 -6  = -30 - 6 = -36

 B.  (x - 3²)(y-6)

          ( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30

C.  x - 3² . (y-6) = -1 - 9.(3-6)

                         = -1-9.-3
