Answer:
±6
Step-by-step explanation:
Given the mathematical expression;
√36 < √42 < √49
But, √36 = 6 * 6 = 6²
√49 = 7 * 7 = 7²
Simplifying further, we would substitute the new values respectively;
±[6] < √42 < ±[7]
Therefore, evaluating √36 is equal to ±6.
x*x=152
x2=152
Take square root.
x=±√152
x=√238
or
x=−√238
Answer: -270
Step-by-step explanation:
First, simplify the exponent
Then, distribute
Then, subtract(add a negative)
Hope it helps <3 :)
if ac is a and bc is b, then ab can be c. now we use Pythagorean method. 16 squared is 156 and 12 squared is 144. added together they are 400. 400 to the square root is 20. Your answer is 20
