<span>(f⋅g)(x)=f(x)*g(x)
</span>f(x)*g(x) = (x⁴−9)(x³+9)=x⁴x³+9x⁴-9x³-81=x⁷+9x⁴-9x³-81
(f⋅g)(x)=x⁷+9x⁴-9x³-81

Answer:

-21 = 6t

Step-by-step explanation:

3t - 7 = 5t

Subtract 3t from each side

-7 = 2t

Multiply each side by 3 to get 6t

-7*3 = 2t*3

Answer:

The answer is 10⁴ × 4⁵.

Step-by-step explanation:

First, you can seperate the fraction :

$\frac{ {10}^{4} \times {4}^{10} }{ {4}^{5} }$

$= {10}^{4} \times \frac{ {4}^{10} }{ {4}^{5} }$

Next, you have to apply Indices law :

${a}^{m} \div {a}^{n} = {a}^{m - n}$

So for this question :

${10}^{4} \times \frac{ {4}^{10} }{ {4}^{5} }$

$= {10}^{4} \times {4}^{10 - 5}$

$= {10}^{4} \times {4}^{5}$
