Answer:
Explanation:
√36 = 6
V36 = 6
3^-2 = 1/3^2 = 1/9
So, V36 ÷ 3^-2 = 6 ÷ 1/9 = 6 x 9 = 54
4³ = 4 x 4 x 4 = 64
4³÷8 = 64 ÷ 8 = 8
Therefore, the expression simplifies to:
0.666(54) + 8 = 36 + 8 = 44
To solve the second expression:
71425 is a composite number, so we need to factorize it to simplify the expression.
First, we can find the prime factorization of 425:
425 = 5 x 5 x 17
Next, we can use the rules of exponents to simplify the expression:
7√425 = 7√(5 x 5 x 17) = 7 x 5√17
Therefore, the simplified value of the expression is 7 x 5√17.
