PEMDAS is the order of operations....it is the order u solve equations.
P = parenthesis....u solve what is in parenthesis first
E = exponents...u solve the exponents next
M = multiply , D = divide....starting from left and going right, u do all the multiplying and dividing
A = addition, S = subtraction...starting from left and going right, u do all the addition and subtraction
Idk what it has to do with simplifying but what I would do is multiply 1 times 3. That gives u 3. Then add Ben's one hour and Brooke's 3 hours together. That gives u 4 hours total.
Volume of cube =a^3
2744=a^3
by making prime factors of 2744
2*2*2*7*7*7=a^3
2^3*7*3=a^3
by taking cube root on both sides
2*7=a
14=a
so<span> the length of its edge =14</span>
The answer is B estimated number is 20
