When you multiply a number with an exponent by a number with an exponent, you add the exponents together.

For example:

x^{2} *x^{3} =x^{2+3}=x^5

y^{1} (y^3)=y^{1+3}=y^4

2^2*2^3=2^{2+3}=2^5


When an exponent is negative, you move it to the other side of the fraction to make the exponent positive

For example:

x^{-2}  or  \frac{x^{-2}}{1}=\frac{1}{x^2}

\frac{1}{y^{-3}}=\frac{y^3}{1}  or  y³



So:

4^3*4^{-5}=4^{3+(-5)}=4^{-2}

4^{-2}=\frac{1}{4^2}=\frac{1}{16}=0.0625


a.) correct

b.) correct

c.) incorrect

d.) correct

e.) correct

f.) incorrect

g.) incorrect

Answer: See explanation

Step-by-step explanation:

Your question isn't complete. First and foremost, to be able to solve this, we need to know the total marks of the examination.

Let's assume that the total marks for the exam is 80. Since Donte scored 55 on his mastery exam, the percent that he score will be:

= 55/80 × 100

= 68.75%
