Thanks to all
To find the closest value to √70, we need to calculate the actual value of √70 and compare it with the given options.
Square root of 70 can be approximated as follows:
√70 ≈ √(7 × 10)
Since √(7 × 10) = √7 × √10, we can simplify further:
√7 × √10
Now, we need to find the approximate values of √7 and √10 individually:
√7 is approximately 2.65 (since 2.65² = 7)
√10 is approximately 3.16 (since 3.16² ≈ 10)
Multiplying these two approximated values:
2.65 × 3.16 ≈ 8.34
Therefore, √70 is closest to the value of 8.
Comparing with the given options, we see that option B, 8, is the closest value to √70.
