(1 point) Use differentials to approximate the given values by hand. Provide, 4 decimal digits of accuracy. ( Note: Only use a calculator for routine arithmetic (addition, subtraction, multiplication, division) as part of the approximation by differentials. If you use your calculator to obtain a result directly (i.e., taking powers or roots), then your answer may be different than the requested approximation.) 8.052 ~ 7.932 ~ 5.06' ~ 4.98' ~
