1 x 81, 3 x 27, 9 x 9.
the eisest way to find square root of something , is to see what number x itself = that number .... so EXAMPLE:what is the square root of 81? this is how you will find it.....so what number x itself gives me 81? it's 9 because 9x9=81 so the square root of 81 is 9
To evaluate (3 \times 27), you can simply multiply the two numbers together. Calculating this gives (3 \times 27 = 81). Therefore, the result of evaluating (3 \times 27) is 81.
81
The multiples of 81 are infinite. The factors of 81 are: 1, 3, 9, 27, 81.
No, these are the factors of 81: 1, 3, 9, 27, 81.
Depending how you read this question it is either 81/100 of 1 which gives 0.81% or it is 81 of 100 which gives 81%.
92 = 81
The tenth of 81 is calculated by dividing 81 by 10. This gives you 8.1. Therefore, the tenth of 81 is 8.1.
9
One half times 81 is 40.5. This is calculated by multiplying 81 by 0.5, which gives you 40.5.
72 less than 81 is calculated by subtracting 72 from 81. This gives us 81 - 72 = 9. Therefore, 72 less than 81 is 9.
-9 or +9.
4 times 81 = 324
The two answers are -9 and +9.
81 + 16
81 raised to the 4th power is calculated as ( 81^4 ). Since ( 81 = 3^4 ), we can rewrite it as ( (3^4)^4 = 3^{16} ). Calculating ( 3^{16} ) gives us 43,046,721. Thus, ( 81^4 = 43,046,721 ).
Use your calculator to calculate the square root of 81. Or use trial-and-error, to see which number, when multiplied by itself, gives you 81. (Hint: In this case, it is an integer.)
