Answer:
0
Step-by-step explanation:
Simplify the following:
81^(1/4) - 8 216^(1/3) + 15 32^(1/5) + sqrt(225)
Hint: | Simplify radicals.
216^(1/3) = (6^3)^(1/3) = 6:
81^(1/4) - 86 + 15 32^(1/5) + sqrt(225)
Hint: | Simplify radicals.
32^(1/5) = (2^5)^(1/5) = 2:
81^(1/4) - 8×6 + 15×2 + sqrt(225)
Hint: | Simplify radicals.
81^(1/4) = (3^4)^(1/4) = 3:
3 - 8×6 + 15×2 + sqrt(225)
Hint: | Multiply -8 and 6 together.
-8×6 = -48:
3 + -48 + 15×2 + sqrt(225)
Hint: | Multiply 15 and 2 together.
15×2 = 30:
3 - 48 + 30 + sqrt(225)
Hint: | Look for the difference of two identical terms.
(-48 + 30 + sqrt(225)) + 3 = 0:
