Answer:
a.) b⁷÷b⁴
= <u>b⁷</u>
b⁴
= b^7-4
= b³
b.) <u>x </u><u> </u><u>×</u><u> </u><u> </u><u>x⁵</u>
x² × x
= <u>x</u><u>^</u><u>1+</u><u>5</u>
x^2+1
= <u>x⁶</u>
x³
= x^6-3
= x³
So, first turn your fractions into decimals. ⅞ = 0.875 which rounded is 0.88. 4/5 = 0.8. Next, put the decimals into the equation to replace the fractions. 0.88 + 4.2 - 0.8. Next solve the problem. So 0.88 + 4.2 = 5.08. Now your equation should look like this 5.08 - 0.8. Then subtract 0.8 from 5.08 which gives you 4.28. So 4.28 is your answer.
