Answer:
5a²+22a+8
Step-by-step explanation:
(5a×a)+(5a×4)+(2×a)+(2×4)
=5a²+20a+2a+8
=5a²+22a+8
Answer:
6^3= 216
4^4=256

For both of these questions you want to raise every part to the 4th or 2nd power. Just remeber that a power raised to a power is just multiplied.
3.)
3^4 = 3×3×3×3 = 9×9 = 81
x^4 = 1×4 = 4 so x^4
2^4 = 2×2×2×2 = 4×4 = 16
so

4.)
2^2 = 2×2 = 4
5^2 = 5×5 = 25
(n^9)^2 = 2×9 = 18 so n^18
so

Hope this helps!
If they're similar it would be 72, 36x2=72.
X^(1/7)x^(1/7)x^(1/7)x^(1/7)
Well the rule for multiplying similar bases with exponents is:
(a^b)(a^c)(a^d)=a^(b+c+d), so in this case:
x^(1/7+1/7+1/7+1/7)
x^(4/7)
In words that is x raised to the 4/7 th power or the seventh root of x raised to the 4th power.
