Which expression is equivalent to 15a^8b^4/5a^4b
LekaFEV [45]

Answer: The given expression \frac{15a^8b^4}{5a^4b} simplified to  3a^4b^3

Step-by-step explanation:

Given : expression \frac{15a^8b^4}{5a^4b}

We have to simplify the given expression \frac{15a^8b^4}{5a^4b}

Consider the given expression \frac{15a^8b^4}{5a^4b}

Divide the numbers \frac{15}{5}=3

=\frac{3a^8b^4}{a^4b}

Apply exponent rule, \frac{x^a}{x^b}\:=\:x^{a-b}

We have,

\frac{a^8}{a^4}=a^{8-4}=a^4

=\frac{3a^4b^4}{b}

Cancel out common factor b,

We have

=3a^4b^3

Thus, the given expression \frac{15a^8b^4}{5a^4b} simplified to  3a^4b^3

HELP!!! Which of the following is not a perfect square trinomial? A. 169 – 26y + y2 B. 81 + 18y + y2 C. 64 + 8y + y2 D. 25 + 10y
natita [175]
Let's review the options:
A. 169-26y+y^2 can be factorised into (13-y)(13-y)
B. 81+18y+y^2 can be factorised into (9+y)(9+y)
C. 64+8y+y^2 cannot be factorised into double brackets
D. 25+10y+y^2 can be factorised into (5+y)(5+y)

Therefore your answer is the odd one out, C.
