Question

8th standard :
Hence find the value of (370)²​

Answer 1

Answer:

Step-by-step explanation:

√370 = 19.2354

19.2354² = 370

Now, we will do the operations in opposite order where we first square 370 and then calculate the square root of the result:

370² = 136900

√136900 = 370

You may also find this math rule interesting when dealing with a problem like the square root of 370 squared:

√x² = √x · √x

It also proves that the square root of 370 squared equals 370.

√370² = √370 · √370

√370 · √370 = 19.2354 · 19.2354

19.2354 · 19.2354 = 370

Answer 2

Answer:

136900

Step-by-step explanation:

Using the identity of $(a+b)^{2}$ = $a^{2}$+$2ab$+$b^{2}$

Let a = 300 and b = 70

$300^{2}$ + $2*300*70$ + $70^{2}$

90000 + 42000+ 4900

136900
