1 هریک از عدد های داده شده را با نماد علمی نمایش دهید:
\(\begin{array}{l}245000 = \\\\0/005 = \\\\1404 = \\\\150,000,000 = \\\\0/000061 = \\\\0/1275 = \end{array}\)
\(\begin{array}{l}245000 = 2/45 \times {10^5}\\\\0/005 = 5 \times {10^3}\\\\1404 = 1/404 \times {10^3}\\\\150,000,000 = 1/5 \times {10^8}\\\\0/000061 = 6/1 \times {10^{ - 5}}\\\\0/1275 = 1/275 \times {10^{ - 1}}\end{array}\)
2 نمایش اعشاری عددهای زیر را بنویسید:
\(\begin{array}{l}5/2 \times {10^{ - 2}} = \\\\2/28 \times {10^8} = \\\\6/01 \times {10^{ - 2}} = \\\\7/304 \times {10^{ - 5}} = \\\\9/4612 \times {10^9} = \\\\1/1 \times {10^4} = \end{array}\)
\(\begin{array}{l}5/2 \times {10^{ - 2}} = 0/0052\\\\2/28 \times {10^8} = 228,000,000\\\\6/01 \times {10^{ - 2}} = 0/0602\\\\7/304 \times {10^{ - 5}} = 0/00007304\;\\\\9/4612 \times {10^9} = 9,461,200,000\;\\\\1/1 \times {10^4} = 11000\;\end{array}\)
