(4^p*4^1)^3) =4^15

add the exponents

(4^(p+1))^3 = 4^15

multiply the exponents

(4^3(p+1))= 4^15

the exponents have to be the same

3(p+1) = 15

divide by 3

p+1 = 5

subtract 1

p =4

Eric is not correct

p=4

75% of 48 explain the process too!

weqwewe [10]

Let us consider 48 as 100%
so,
48------------->100
x -------------->75
therefore,
100*x=48*75
x=(48*75)/100
x=36

X2y4(x2 - 16) - 9y4(x4 - 16) how do i simply this?

e-lub [12.9K]

Answer:

The simplified expression is given as

$8x^2y^4(17x^2-2)$

Step-by-step explanation:

step one:

Given the expression

$x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)$

step two:

First, let us open the bracket we have

$x^2y^4(x^2 - 16) - 9y^4(x^4 - 16)\\\\x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\$

step three:

collect like terms we have

$x^4y^4-16x^2y^4-9x^4y^4+144x^4y^4\\\\x^4y^4-9x^4y^4+144x^4y^4-16x^2y^4\\\\-8x^4y^4+144x^4y^4-16x^2y^4\\\\136x^4y^4-16x^2y^4\\\\\\$

step four:

we can now factor out $8x^2y^4$ we have

$8x^2y^4(17x^2-2)$
