The Answer is 20

Explanation
If a is 4 then 4 to the power of 2 would be 16. If b is -2 and it is applied to the power of 2. Then it would be -4. But since there is another minus sign behind the B, you would make the sign a addition sign. So it would basically be 16 plus 4, which is 20

Can somebody help me solve 8^4v + 5 = 31 ?
bezimeni [28]
8^{4v}+5=31
minus 5 both sides
8^{4v}=26
take the log₈ of both sides
4v=log₈26
divide both sides by 4
v=(1/4)log₈28

if yo use calculator
go back
8^{4v}=26
take ln of both sides
4vln8=ln26
divide both sides by (4ln8)
v=(ln28)/(4ln8)
evaluate
v≈0.40061291017147

Using the method of prime factors

8 = 2 × 2 × 2 = 2³
