Basics Of Surds Together With Indices Inwards Quantitative Aptitude

Dear Students, Surds together with Indices are the os of algebra. Rules of Surds together with Rules of Indices nosotros convey given below, y'all must know these formula to solve the questions based on it smoothly.

Important Rules of Indices:

a^m×aⁿ=a^m+n

a^m/aⁿ=a^m-n

(a^m)ⁿ=a^mn

(ab)ⁿ=aⁿbⁿ

(a/b)ⁿ=aⁿ/bⁿ

a⁰=1

Important Rules of Surds:

Once y'all yell back the higher upwards formula, y'all volition last able to produce whatsoever complex questions based on it. We are doing some questions amongst shortcut solutions.

Q1. 102^?×102^5.6 = 102^3.4

Shortcut Solution:

102^?×102^5.6 = 102^3.4

Or, 102^?+5.6 = 102^3.4

Or, ?+5.6 = 3.4

Or, ?=3.4-5.6=-2.2

Q2. If  (a/b)^x-1=(b/a)^x-3 then honour the value of x.

Shortcut Solution:

(a/b)^x-1=(b/a)^x-3

tin flaming last written equally :

After cross multiplication :

(a)^(2x-4)=(b)^(2x-4)

=>(a/b)^(2x-4)=1

=>(a/b)^(2x-4)=(a/b)^0

=> 2x-4=0

=>x=4/2

=>x=2

Q3. If 10^0.48 = x, 10^0.70 = y together with x^z = y², together with thence the value of z is unopen to:

Shortcut Solution:

Do this enquiry inwards 3 steps:

Step1: zlog(10^0.48)=2log(10^0.70)

Step2: z✕0.48=2✕0.70 (Log10=1)

Step3: z= 2.9

Q4. Given that 5^a = 3125, together with thence the value of 5^{(a - 3)} is:

Shortcut Solution:

5^(a-3) = 5^a/5^3.

= 3125/125.

= 25

Q5. If 3^{(x - y)} = 27 together with 3^{(x + y)} = 243, together with thence x=?

Shortcut Solution:

x-y = 3

x+y = 5

________ 

2x = 8

________ 

2x/2 = 8/2.

x = 8/2.

so, x = 4.
