Remember, the exact value cannot involve any rounding or estimates. Now, let's solve this problem. First, we have to translate it into an expression:
√72 - √8 + √128 separate the terms into square roots
√36·2 - √4·2 + √64·2 square root the terms that you can
6√2 - 2√2 + 8√2 they have like radical terms, so combine the terms
6 - 2 + 8 = 12 the coefficients are 12 when combined
12√2 this is the EXACT VALUE of the expression
Hope this helps!
Answer:
b)−2° C
Step-by-step explanation:
hello! To solve this problem you should remember how are the operations with negative numbers, for this the only thing we must do is make a subtraction between the initial temperature (8° C) and the negative change of temperature (10° C)
Ti= initial temperature =8° C
ΔT= temperature change =10° C
new temperature=Ti-ΔT
new temperature=8° C-10° C=-2° C
in conclusion the answer is -2° C
