What is 2a squared if A is 3?

thus, if a=3, then 2a squared = 2×3 times 2×3 = 6 times 6 or 36. This is different from 2a^2, which means 2 times the square of a, or 2xaxa. In this case, 2a^2 would be 2x3x3, or 18.

What is the value of 2 Power 3 by 2?

Explanation: 2 to the 3rd power can be written as 23 = 2 × 2 × 2, as 2 is multiplied by itself 3 times. Here, 2 is called the “base” and 3 is called the “exponent” or “power.” In general, xn means that x is multiplied by itself n times.

Which is the correct answer for 2A squared?

According to BIDMASS, indices come before multiplication and so 3 squared is 9. 9 multiplied by 2 is 18. Therefore the answer is 18. However if its 2a whole squared the answer will be 36 because 2 multiplied by 3 is 6 and 6 squared it 36.

How is 3A squared equal to the number 27?

If a=-3 then 3a squared will be equal to 27. This is because of BEDMAS (the order of operations). In BEDMAS, the exponents come before multiplication which means you must do -3 squared first. -3 squared is equal to -3*-3 which equals 9 (two negatives equal a positive). Then you multiply the 3 with the 9 which is equal to 27.

How to find out a which is 3 squared?

First, you have to find out a which is 3. This must mean that 2a squared is 2 multiplied by 3 squared. Now you have to solve this equation by going in a particular order where I am from, we call it BODMAS (brackets, order, division and multiplication, addition and subtraction.

Is the number n squared a perfect square?
