What is 81 times 70 equal?
81 times 70 equals 5,670. This can be calculated by multiplying 81 by 70, which results in 5,670. To do this, you would multiply the tens place of 81 (which is 8) by 70, resulting in 560, and then multiply the ones place of 81 (which is 1) by 70, resulting in 70, and finally add these two products together to get the final answer of 5,670.
How do you solve 3 to the power of what equals 81?
34 = 81 so x is 4
Solve 3x - 5x plus 11x equals -81?

How do you solve x2-81 equals 0?
2x - 81 = 0 Add 81 to both sides. 2x - 81 + 81 = 0 + 81 Substitute, -81 + 81 cancels out. 2x = 81 Divide by 2. x = 40.5 Above answer would be correct if your question was 2x but it was x2 so using the same method you would get x2 = 81 here the opposite of the square is the square root x = 9
How do you find out how to do 81 is 70 percent of?
Divide 81 by 70%. ===> That is, solve the problem: (81) / (0.7)
How do you solve x2 81 equals 0?
x: x2 - 81 = 0

How do you solve x squared equals negative 81?
x2=-81take the square root of both sidessince 81 is negative you need to take 81 times i when i=-1 then solve as the square root of 81. your answer is x=9i
How do you solve x2-81 equals 0?
2x - 81 = 0 Add 81 to both sides. 2x - 81 + 81 = 0 + 81 Substitute, -81 + 81 cancels out. 2x = 81 Divide by 2. x = 40.5 Above answer would be correct if your question was 2x but it was x2 so using the same method you would get x2 = 81 here the opposite of the square is the square root x = 9
What equals to 7 6x 9x 9?
This is poorly typed, so I will assume you mean "what does 76 * 9 * 9 equal?"This can be done with a calculator or by hand. (* = multiplied by)By hand you would simply do long multiplication of 76 * 81 (since you should know that 9 squared is 81)Note that on each line, everything in bold represents the same number (which equals 5670) and everything in italics represents the same number (which equals 486)76 * 9 * 9 = 76 * 81= (70 * 81) + (6 * 81)= ((70 * 80) + (70 * 1)) + ((6 * 80) + (6 * 1))= (5600 + 70) + (480 + 6)= 5670 + 486= 6156
Solve the proportion 3 over 9 equals x over 81?
3/9 = x/81 x = 27 So: 3/9 = 27/81
What is 70 percent of 81?
115.71%% rate:= 81/70 * 100%= 1.1571 * 100%= 115.71%
How do you solve this type of reasioning such as 92y equals 36 then 9y equals?
92y = 36 y = 36/92 = 9/23 Then: 9y = 81/23
