Cevap:
3) 2√7 - 5√7√9 + √7.√49 = 2√7 - 15√7 + 7√7 = -6√7
4) √6,4 = √64 / √10 = 8/√10
√1,6 = √16 / √10 = 4/√10
√0,4 = √4 / √10 = 2/√10
= 12 / √10 : 2 / √10 = 12/√10 . √10 / 2 = 6
5) 1 + 9/16 = 25 / 16 √(25/16) = 5/4
1 - 15 /16 = 1 / 16 √(1/16) = 1/4 5/4 - 1/4 = 4/4 = 1 pay
0,81 = 81 /100 √(81/100) = 9/10
1,21 = 121 / 100 √(121/100) = 11/10 9/10 + 11/10 = 20/10 = 2 payda
cevap = 1/2
6) 3¹³, 27⁵ = 3¹⁵ , 81³ = 3¹² , 9⁷ = 3¹⁴
81³ < 3¹³ < 9⁷ < 27⁵
7) 4¹² = 2²⁴
512 = 2⁹
2²⁴ : 2⁹ = 2¹⁵ litre boşa akar.
2¹⁵= 32768 litre
sağlaması
4¹² = 16777216 damla
16777216 : 512 = 32768
