Answer:  The correct option is (C) (6x^4-7)(6x^4+7).

Step-by-step explanation:  We are given to factor the following polynomial completely:

P=36x^8-49~~~~~~~~~~~~~~~~~~~~`(i)

We are given to use the following formula:

a^2-b^2=(a+b)(a-b).

We have, from equation (i) that

P\\\\=36x^8-49\\\\=(6x^4)^2-7^2\\\\=(6x^4+7)(6x^4-7).

Thus, the required factors are (6x^4-7)(6x^4+7).

Option (C) is correct.

Help me with this lol value of( 2^3)^2
ss7ja [257]

Answer:

64

Step-by-step explanation:

first, we'll start with the value inside the parenthesis, which is 2³

2³ means to multiply 2 by itself 3 times

so it would be

2×2×2=8

which then means that the expression is now (8)²

now we need to do (8)², which is to multiply 8 by itself twice

8*8=64

hope this helps!
