Simplify square root​

Mathematics
1 answer:
Tasya [4]3 years ago
8 0

Answer:

Here is the rule: when a and b are not negative

√(ab) = √a × √b

Example: simplify √8

√8 = √(4×2) = √4 × √2 = 2√2

(Because the square root of 4 is 2)

In other words 2 x 4 = 8 = √2 x 4 but 4 can be simplified more (2 x 2) so 2 (previous 4) moves to the left of the square root leaving  2√2

To simplify a square root: make the number inside the square root as small as possible (but still a whole number)

or you can use a simplifying square root calculator.

3c=2(c-1) in a verbal expression
kifflom [539]

9514 1404 393

Answer:

  "three times a number is the same as twice the difference of the number and 1"

Step-by-step explanation:

3c is "three times a number"

2(c -1) is "two times the difference of the number and 1"

When writing the description of the right-hand side, one needs to be careful to write it so there is no ambiguity with respect to what is being multiplied by 2. For example, if you say, "two times one less than the number", it is not clear whether that is c -2×1 or 2×(c -1).

A suitable description is ...

three times a number is the same as twice the difference of the number and 1
