Answer:
Option A is correct
Step-by-step explanation:
Given:
There are four option is given.
We need to find correct option.
Now we check the given option.
Option A.
Now we simplify the left side of the equation.
Simplify
And 2.4 replaced by
So the value of left side of the equation is equal to the value of right side of the equation.
Therefore, option A is correct
Answer:
None of the expressions in the option is equal to 10 x(13).
Step-by-step explanation:
The answer can be verified by calculating the values of the expression in the question, those of each options, and then compare as follows:
Value of the expression = 10 x (13) = 10 x 13 = 130
Therefore, we have:
A. 10 + (1+3) = 10 + 4 = 14 130
B. (10 x 1)+3 = 10 + 3 = 13 130
C. 10 + (1x3) = 10 + 3 = 13 130
D. (10 * 1)3 = 10 * 3 = 30 130
Based on the calculations above, none of the expressions in the option is equal to 10 x(13).
Answer:
Assuming the variable is included under the radical,
-40k²√(10)
Step-by-step explanation:
First we will simplify the first factor,
We will write 20 as a product of factors:
We know the square root of 2 is 2, so we pull a 2 out:
Now we will simplify the second factor,
We will rewrite 8 as a product of factors, as well as the variable:
The square root of 2 is 2, so we pull a 2 out. Additionally, the square root of k² is k, so we pull that out:
This gives us the product
Multiplying the coefficients, we have
Multiplying the two radicals, we have
The square root of k² is k, so we pull a k out, leaving
