this questions are about what

Step-by-step explanation:

Using suitable identity find: (i) 482 (ii) 962 (iii) 2312 – 1312 (iv) 97 × 103 (v) 1812 – 192 = 162 × 200 .

Answer 2

Answer:

(1)(99)3=(100−1)3=(100)3−3(100)(1)(100−1)−(1)3

=1000000−29700−1

=970299

(2)(1001)2=(1000+1)2=(1000)2+2(1000)(1)+(1)2

=1000000+2000+1

=1002001

(3)(105)3=(100+5)3=(100)3+100(5)(100+5)+53

=1000000+157500+125

=1157625

(4)105×108

=(100+5)(100+8)

=10000+800+500+40

11840

(5)91×106

=(100−9)(100+8)

=10000+600−900−54
