<u>How to solve exponent calculations</u>
Simplify each side of the equation. Set the equation equal to zero. Factor the left side of the equation. Set factors equal to zero and solve.
To solve basic exponents, multiply the base number repeatedly for the number of factors represented by the exponent. If you need to add or subtract exponents, the numbers must have the same base and exponent.
Answer:
no
Step-by-step explanation:
86.90 - 15.00 = 71.9
71.9 * .18 = ~ 12.94
71.9 + 12.94 = $84.84
Answer:
BC≈1.71
Step-by-step explanation:
The cosine of an angle is the adjacent side relative to that angle divided by the hypotenuse.
cos(70)=BC/5
BC=cos(70)*5≈1.71
The angle A with 85, 10x is a 1345
