The following questions are calculated by simple method: (1) 2.9 × 0.45 + + 0.29 × 4.2 + 0.029 × 13 (2) 3.84 × 9.6 + 0.96 × 61.6
（1）2.9×0.45+0.29×4.2+0.029×13 =2.9×0.45+2.9×0.42+2.9×0.13=2.9×(0.45+0.42+0.13)=2.9×1=2.9(2)3.84×9.6+0.96×61.6=3.84×9.6+6.16×9.6=(3.84+6.16)×9.6=10×9.6=96
What is 15 ° 30'5 "equal to"?
15×3600＋30×60＋5＝55805
Using a simple method to calculate: (1 / - 0.25) ^ 14 * 2 ^ 30 = 4 ^ 29, right?
Yes
（1/-0.25）^14*2^30
=[1/(-1/4)]^14*2^30
=(-4)^14*2^30
=4^14*2^30
=(2^2)^14*2^30
=2^28*2^30
=2^(28+30)
=2^58
=4^29
