दिले:

सरलीकृत करा: ((४ ) × (१)/(६४ )) + १०

संकल्पना:

घातांक नियम आणि सरलीकरण

वापरलेले सूत्र:

(a m ) n = a m×n

a m / a n = a mn

गणना:

आमच्याकडे आहे,

⇒ ((४ ) × (१)/(६४ )) + १०

प्रथम, कंसात सोपे करा:

⇒ (4 4×2 × (1)/(64 2 )) 2 + 10

⇒ (4 8 × (1)/(64 2 )) 2 + 10

64 = 4 3 पासून, आपण लिहू शकतो:

⇒ (4 8 × 1/(4 3×2 )) 2 + 10

⇒ (४ × १/(४ )) + १०

⇒ (4 8-6 ) 2 + 10

⇒ (4 2 ) 2 + 10

⇒ ४ २×२ + १०
