To simplify the expression (15^−3 ⋅ 4^7)^0over4^−3, we can apply the exponent rules:
First, let's simplify the exponents separately:
15^−3 = 1/(15^3) = 1/3375
4^7 = 16384
Now, let's simplify the expression inside the parentheses:
(1/3375 ⋅ 16384)^0 = 1^0 = 1
Finally, let's simplify the denominator of the exponent:
4^−3 = 1/(4^3) = 1/64
Putting it all together:
(15^−3 ⋅ 4^7)^0over4^−3 = 1^0/1/64 = 1/(1/64) = 64
Therefore, the equivalent expression is 64.

To simplify the expression (2^−3⋅9^3)^−4over2^9 ⋅9^−10 with only positive exponents, we can apply the exponent rules:
First, let's simplify the exponents separately:
2^−3 = 1/(2^3) = 1/8
9^3 = 729
Now, let's simplify the expression inside the parentheses:
(1/8 ⋅ 729)^−4 = (729/8)^−4
Next, let's simplify the numerator and denominator of the second fraction:
2^9 = 512
9^−10 = 1/(9^10) = 1/3486784401
Putting it all together:
(2^−3⋅9^3)^−4over2^9 ⋅9^−10 = (729/8)^−4/512⋅(1/3486784401) = (8/729)^4/512⋅(1/3486784401) = (8^4/729^4)/(512/3486784401)
Simplifying further:
(8^4/729^4)/(512/3486784401) = (4096/531441)/(512/3486784401) = (4096/531441) × (3486784401/512) = 2^12/9^2
Therefore, the equivalent expression is 2^12/9^2.
First, let's simplify the exponents separately:
2^−3 = 1/(2^3) = 1/8
9^3 = 729
Now, let's simplify the expression inside the parentheses:
(1/8 ⋅ 729)^−4 = (729/8)^−4
Next, let's simplify the numerator and denominator of the second fraction:
2^9 = 512
9^−10 = 1/(9^10) = 1/3486784401
Putting it all together:
(2^−3⋅9^3)^−4over2^9 ⋅9^−10 = (729/8)^−4/512⋅(1/3486784401) = (8/729)^4/512⋅(1/3486784401) = (8^4/729^4)/(512/3486784401)
Simplifying further:
(8^4/729^4)/(512/3486784401) = (4096/531441)/(512/3486784401) = (4096/531441) × (3486784401/512) = 2^12/9^2
Therefore, the equivalent expression is 2^12/9^2.
