Sqrt72 = sqrt(9x8) = 3sqrt8 = 3(sqrt(4x2)) = 3(2sqrt2) = 6 sqrt(2)
2. sqrt x = x^½. Rules of indices states for a power of a power, you times them.
so (x^28)^½ = x^14
Answer:
228 cubic centimeters
Step-by-step explanation:
Find the volume for the blue box: 8 x 1 x 6 = 48
Find the volume of the orange box: 6 x 6 x 5 = 180
48 + 180 = 228
If you want to find the whole, you have to start by dividing 100% by 60%, so you can multiply that quotient by 3/4 to find the whole. 100/60=10/6=5/3. That means 5/3*60%=100%, so 3/4*5/3=whole. 3/4*5/3=15/12, and simplify to get 5/4, or 1 1/4. 3/4 is 60% of 1 and 1/4, or 5/4.
Answer:
13
Step-by-step explanation:
5x = 65
x = 65/5
x = 13
