How do u simplify . Express final answer using positive exponents.
2^3=
(B^4)^-3=
2^3 is 8 and i think the second one is B^-12 im not ppositive though
(2a5b3)a4-16a20b7
To simplify an expression and express the final answer using positive exponents, you need to apply the rules of exponents. Let's go through each expression separately:
1. 2^3:
To simplify 2^3, you need to evaluate the exponent, which means multiplying the base (2) by itself the number of times indicated by the exponent (3). In this case, it would be 2 * 2 * 2 = 8. Since the exponent is already positive, the result is already in the desired form.
So, 2^3 = 8.
2. (B^4)^-3:
To simplify (B^4)^-3, you need to apply the power of a power rule. According to this rule, you multiply the exponents when you raise a power to another power. In this case, you need to multiply the exponents 4 and -3.
So, (B^4)^-3 = B^(4 * -3) = B^(-12).
Now, to express the final answer using positive exponents, you can rewrite the expression with a positive exponent of 1 over the base. Recall that any negative exponent can be converted to a positive exponent by taking the reciprocal.
So, B^(-12) = 1 / B^12.
Therefore, the simplified expression with positive exponents is 1/B^12.
