How do you write out (x^3) (x^-2) into an equivalent expression

Solution:

Given that,

Given expression is:

We have to write the equivalent expression

Use the following law of exponent

Therefore,

Here the base is same and exponents are 3 and -2

Thus we get a equivalent expression as:

Thus the equivalent expression is x

rx and sx

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
