All laws of exponents Class 9

So basically exponents or powers denotes the number of times a number can be multiplied. If the power is 2, that means the base number is multiplied two times with itself. Some of the examples are: 3 4 = 3×3×3×3. 10 5 = 10×10×10×10×10. 16 3 = 16 × 16 × 16. Suppose, a number 'a' is multiplied by itself n-times, then it is. The exponents can be numbers or constants; they can also be variables. Exponents are generally positive real numbers, but they can also be negative numbers. Laws of exponents: If a and b are any real numbers, and m and n are rational numbers then, a m × a n = a m+n a m a n = a m-n, m > n. (a m) n = a mn (a m × b m) = (a × b) m. a m b m = (a.

For example: (1) 6 = (1) 8, but 6 ≠ 8. If a ≠ ±1 or 0, then x = y. If a = 1, then x, y may be any real number. If a = −1, then x, y may be both even or both odd. If a = 0, then x, y may be any non-zero real number. But if we have to solve the equations like. Here are some examples: 3x + 1 = 9 5t + 3 × 5t − 1 = 400. If we can write a single term with the same base on each side of the equation, we can equate the exponents. This is one method to solve exponential equations. Important: if a > 0 and a ≠ 1 then: ax = ay then x = y (same base) Also notice that if a = 1, then x and y can be different CBSE Class 9 Maths new syllabus for 2021-22 is available here for download in PDF format.
